DA Problem with SRT installed on P-01 Omega
« on: April 13, 2019, 01:06:59 AM »
My SRT kit for my P-01 Omega arrived today.
I installed
-the disconnector & safety block lever that came in the kit
-factory DA roller that I polished
-factory pins that I polished
-reduced power Trigger Return Spring
-15# hammer spring

When I pull the trigger quickly in DA, the hammer fires correctly and it'll cock on a subsequent pull.
When I pull the trigger slowly in DA, the hammer hangs up - sometimes I'll get a delayed fire & sometimes I get no fire at all.

-sear & hammer are factory original and have not been polished or altered in any way.
-trigger bar was polished but worked fine previously
Here's video (hopefully the link works)

Any ideas?

I re-installed the factory discnnector and lever this morning and the action works as it should.  I don't know why there's an issie with the CGW parts.

David from CGW emailed me back and said it's a timing issue caused by the factory roller.

     Hiya Due51 and thx for the thread and excellent vid demonstrating the issue. But I'm a little slow,so what does it being a timing issue by the roller actually mean in terms of a fix??? New part? More polish? Thx. Be well.

It has to do with the geometry of the disconnector, lever, and bearing.
The CGW disconnector and lever are fractions of an inch larger than the OEM parts.  So when the trigger bar engages the CGW disconnector & lever, it's doing it sooner (I believe) and requires the large .220 bearing to force the trigger bar down a nano-second sooner.

At least that's how I unrestrand it.

The new CGW bearing arrived today.
I installed it along with the disconnector and safety block lever that came with the SRT kit and everything seems to be working properly.  I'm hoping to take it to the range tomorrow for a test run.  I'm anxious to get it in my EDC rotation.

Glad to hear that you got it worked out. Thank you for the follow up we all learn from this stuff.
Will work for CZ pics! (including but not limited to all CZ clones)
